6 Claims.

The invention relates to improvements in shoe sole laying and lastingmachines and has for its primary object the provision of an improvedmachine or appliance of the character indicated which is capable ofeconomical production and highly eiiicient in use.

Another object of the invention is the provision of a construction ofthe character indicated so constructed and arranged as to facilitate theproper shaping of a shoe and fitting of the sole thereto. v

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification and in which- Fig. 1 is atop plan View of the clamping arrangement employed in the device;

Fig. 2 a side View of the complete device on a reduced scale;

Fig. 3 a partial section taken substantially on line 3 3 of Fig. l; and

Fig. 4 a section taken substantially on line 4 4 of Fig. 1.

The embodiment of the invention illustrated in the drawings comprises asuitable supporting frame li; generally in the form of a. table. Avertical last spindle II is arranged as shown at the topV oi said tableadjacent the front end thereof. The shoe last of usual construction andcarrying a pre-welt shoe I2 is provided with the usual socket to receivethe upper end of the spindle I i as will be readily understood.

Two laterally swinging plates or wipers I3 are arranged as shown onopposite sides of the shoe and last, each clamping plate being providedwith curved beveled edges I4 nicely shaped as best shown in Fig. 1 tothe contour of the corresponding sides of the rear portion of thepre-welt shoe on the last. At the inner ends the clamping plates I3 arereinforced at top and bottom by reinforcing plates l5 and carrytrunnions I3 fitting into sockets in the tops of supporting posts Il andwhereby the clamping plates .I3 are pivoted to swing toward and awayfrom the last in planes just below the welt of the pre- 50?, welt shoeon the last.

ly over` the tops of the posts I8 and are provided with stop blocks i8which limit their inward swing at the proper positions. At their forwardends the clamping plates I3 are provided with handle members I9 arrangedto be secured Q- The plates I3 pass free' gether in their innermostportions by a latch member 20 as best shown in Fig. v1.

A third clamping member 2l is arranged as shown to slide in guidegrooves 23 formed in the sides of the supporting frame and also to enterguide grooves 23 formed as best shown in Fig. 4 between the inner edgesof the reinforcing plates which are extended for this purpose, saidthird clamping member thus being caused to operate in the same plane asthe clamping plates i 3. The third clamping member 2I has its inner edge24 beveled and shaped to the contour of the toe portion of the preweltshoe on the last, as will be readily Aunderstood. The clamping plate 2Iis normally held in retracted position by means of a tension spring 25and is connected as shown with the ends of a pair of operating wires 26attached to posts El on the underside thereof. Operating wires 25 leadthence forwardly and downwardly around the guide member 28 where theyare connected with the upper end of a belt or strap 29 in turn connectedwith the foot lever 3D for operating the same.

In use and in operation a pre-welt shoe comprising the usual upper,insole and welt are secured to the last by temporary nails in the usualWay and said last is then placed on the spindle II and nicely adjustedthereon until the plane of the clamping plates 2| and I 3 is arranged topass just under the Welt of the shoe. The edges of the plates I3 arethen fitted around the shoe just under the welt, and tightened andsecured in place about the rear portion of the shoe to shape and holdthe corresponding portions thereu of on the last, as will be readilyunderstood. Then the foot lever 3B is operated to draw the clampingmember 2| into position to similarly clamp about the shoe to shape andhold the toe portion thereof in place on the last. As will be noted, theclamping plates I3 are pivoted to swing on the trunnions I5 which arelocated opposite the toe portions of the last so that when clampingplates I3 are swung inwardly they first engage and position the sides ofthe upper before the heel portions are effectively engaged thusfacilitating the stretching and shaping of the upper to the last. Thenthe nails securing the insole in place are withdrawn, adhesive is apuplied to the insole and welt and the outer shoe sole applied by heavypressure and pounding to be accurately and nicely secured in place. Whenthis has been done the shoe is in condition for removal and sewing andtrimming of the insole.

By this arrangement the shoe soles may be spirit of the invention. I,therefore, do not wish to be limited to the precise details of theconstruction set forth, but desire to avail myself of such variationsand modifications as fall within the scope of the appended claims.

I claim:

1. A device of the class described comprising av pair of opposedclamping members pivoted to swing toward and away from the rear sidesand rear of a last positioned between them, said members being pivotedto swing at points opposite the toe portions of the last and in planeslocated substantially below the welt of a shoe member on said last andshaped to fit the cor- Iresponding shoe sides; means for forcing saidclamping members. toward each other to clamp and shape a shoe upper tosaid last; means for locking said clamping members in clampingpositions; a third clamping member arranged and mounted for movementstoward and away from the toe portion of said last in a plane locatedsubstantially below the welt of a shoe on said last and shaped to fitthe toe portion of the shoe; and means for operating said third clampingmember.

2. A device of the class described comprising a. pair of opposedclamping members pivoted to swing toward and away from the rear sidesand rear of a last positioned between them, said members being pivotedto swing at points opposite the toe portions of the last, and in planeslocated substantially below the welt of a. shoe member on said last andshaped to flt the corresponding shoe sides; means for forcing saidclamping members toward each other to clamp and shape a shoe upper tosaid last; means for locking said clampingl members in clampingpositions; a third clamping member mounted to slide toward and away fromthe toe portion of said last in a plane located substantially below thewelt of a shoe on said last and shaped to fit the toe portion of theshoe; and means for operating said third clamping member.

3.
